For In Loop. Reverse Traverse
Jul 23, 2005Unfortunately, I couldn't find any way to traverse the object array in
reverse order. I'd thought there must be a way to do it with for..in
loop, but couldn't find anything yet.

View 5 Replies View RelatedJQuery :: How Does Traverse DOM
Oct 25, 2011I am pretty new to jQuery, so apologies for such a basic question. But, it seems to me, the DOM is a hierarchical data set, and jQuery runs up and down this set in order render many of its results.I would like to understand, therefore, what method(s) jQuery uses to traverse the DOM. Is it using some form of indexing - a radix tree maybe?Developing the thought, I am wondering if there are any caching or optimisation steps I could take to help it along.I ask because a) I am always curious about these things b) I would like to write the best code I can based upon as much information as I can get and c) I am starting to use Ajax and, it seems to me, that the sequence and timing of asynchronous requests needs to be carefully thought through. If requests to the DOM can ever conflict (logically or otherwise) with requests to a server, I would like to understand how it all works.
View 3 Replies View RelatedTraverse An Array Using A Key?
Jun 29, 2011I have an array called "Prods". Here are the different values in that array:
ProductName, HowManyCalories, ProductImage, LinkFromImage, Description, Price, BuyLink
There are a number of products. I'm just wondering how do I use "ProductName" as a product key to output its unique values?
Eg. the ProductName is "Chocolate Spread" - how do I output the "HowManyCalories" and "Product Image" only from the "Prods" array, based on the key "Chocolate Spread"?

Traverse Array With Onclick?
Apr 10, 2009I'm working on an image gallery at the moment and I'm having some trouble with the array the the images are stored in. The issue I'm having is that I can't figure out how to increase and decrease the current element in an array with the onclick event. Here's what I'm thinking so far:
var imageList = ['a','b','c','d','e'];
var position=0;
currentImage=imageList[position];
if a link with the id of "leftClick" is clicked, then position should decrease by 1 but if a link with the id of "rightClick" is clicked, then position should increase by 1 Both of these conditions should be bound to imageList.length i.e. if (position<0){position=0}; and if (position>imageList.length){position=imageList.length}; So how can I make "position" increase or decrease by clicking a link using the onclick event?

View 3 Replies View RelatedJQuery :: Can't Traverse Newly Created Elements
Dec 8, 2010Consider the following snippet of [code]...
I would expect it to show "2" but instead it shows "0". Why?
It seems the find() method doesn't work on the newly created elements. Do traversing methods only work on elements that are actually in the document? If so, how can I traverse and manipulate freshly created elements prior to inserting them into the dom?
JQuery :: Traverse The XML Properly Without Going Thru The Entire List?
Jan 28, 2011I'm getting some XML back from an ajax call ... it's working as expected.My problem/question is that I don't know how to traverse the XML properly using Jquery.This is what I'm getting back:
<media>
<photos>
<photo id="1" size="s">url/photo1-s.jpg</photo>[code]....
My code currently uses $(this).find("photos").each(function() to get each of the photos, and that works fine.However, the list of photos can be quite large, and I really don't need them all -I'd like to just "grab" the one or two photos I know I need based on the id and size attributes. Is this possible without going thru the entire list?
JQuery :: Select (or Traverse To) IFrame Parent Of A Document?

I get a null set returned when I try$(this).parents().
View 1 Replies View RelatedIE6 Reverse Bug!
Sep 13, 2006I just found out that for IE6 (standard mode and quirks mode), for DOM Level 2 events (haven't tested for DOM Level 1), the event object is available just like in Firefox, that is as the first argument in the event handler function. I named the first argument eent (vokuntarily misspelled eent instead of event) so as to assure myself that IE6 didn't take the variable named event as window event.
CCl: For IE6 and on, no more need to have this ****** code (I hate it):
function eventHandler(event)
{
if (typeof event == "undefined")
{
event = window.event;
}
...
}

Reverse Geolocation, Parsing JSON In IE9?
Sep 11, 2011I'm baffled! I'm coding in HTML5 and getting back the geo coordinates with no problems; I set them as cookies for future reference, then pass them to a reverse geolocation server using $.getJSON in jQuery 1.5.1. I have to parse through the results, but I manage to get the user's US state location (which is my goal) in Firefox, but not in IE.
The JSON appears to be well-formed, and looks like this:
Code JavaScript:
